Elementary Surveying Geomatics presents basic concepts in each fundamental area of modern surveying (geomatics) practice. While introductory, its depth and breadth also make it ideal for self-study and preparing for your licensing examination. It includes more than 400 figures and illustrations to help clarify discussions. Extensive end-of-chapter problems give you opportunities to review and apply what you've learned.
The 16th Edition is updated to provide a state-of-the-art presentation of surveying equipment and procedures. Rewritten end-of-chapter problems illustrate computational procedures. It also includes new discussions of GNSS precise point positioning, small unmanned aerial systems, new datums and more.
